ionic bonding

Question 1

how is ionic bonding formed?

Answer 1

between metals and non-metals

Question 2

what is ionic bonding?

Answer 2

When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions. The resulting compound is called an ionic compound.

Question 3

what is a cation?

Answer 3

metals that form positive ions because they gain electrons to become stable

Question 4

what is an anion?

Answer 4

non-metals form negative ions because they gain electrons to become stable

Question 5

what is an ionic compound?

Answer 5

is a giant structure of ions known as a lattice structure

Question 6

characteristics of an ionic compound?

Answer 6

• high melting points which conduct when molten or in a solution but never solid
• high boiling point because the strong ionic bonds need to be broken
• dissolve in water easily, water molecules surround the separated ions

Question 7

what are balanced ionic half equations?

Answer 7

the charges on the ions have to cancel out to leave an overall charge of zero

Question 8

what charges are group 1 metals have?

Answer 8

1+

Question 9
